This is a serial dilution problem... I don't what sodium cefotaxime is, and certainly I don't know its molar mass. Find its molar mass, and divide the mass by this quantity, and then provide the solution …

It looks like a serial dilution is in order. How about this? Step 1: Dissolve 40 mg of "Lis" in 100 mL of water. " [Lis]" = (40 × 10^"-3" color (white) (l)"g")/"0.100 L" = "0.40 g/L" Step 2: Dilute 1 mL of this …

It's worth knowing that the dilution factor, DF, tells you the ratio that exists between the volume of the diluted solution and the volume of the stock solution. DF = V diluted V stock In your case, the volume …

Here's my take on this. Assuming that the question is not incomplete, your goal here is to figure out the dilution factor, "DF", for the second dilution, and the overall dilution factor for the two dilutions. For …

The idea here is that when a solution undergoes a 1:3 dilution, its final volume increases by a factor of 3. This is done by adding enough solvent to ensure that the total volume of the solution increases by a …

Well this one is easy; of course there is a catch..... When you work with concentrated acids, you ALWAYS add acid to water and never the reverse. This is non-negotiable and it is absolutely …

Aliquot is 15 ml and i made volume makeup upto 50ml.what will be its dilution factor?

Here's how you can do that. A solution's concentration in parts per million, or ppm, tells you the number of grams of solute you get for every 10^6 = 1,000,000 grams of solution. Similarly, a solution's …

Multiply the number that you got in the previous step by the inverse of the number on your dilution tube. For example, if the plate you selected was the #10^-2# plate, you would multiply 10 by #10^2# to get …
